HPCPUNAME Model Strings Supported With MPE/iX Release 7.5 and Possible Bootup Failures
82
For HP e3000 A- and N-Class Servers, the following definitions apply to model strings:
• First term = SERIES e3000
• Second term = family and model, may be variable length
• Third term = number of processors authorized, are only three characters
• Fourth term = frequency of authorized processors, are only two characters
Model strings for newly shipped servers are always properly set by the HP factory or by the US Distributor,
Client Systems. Whenever an HP e3000 Server is upgraded through a chassis upgrade or by the addition of a
processor, the model strings are properly set by the HP field CE doing the installation. Before completing an
installation, HP field CEs should boot the HP e3000 Server to demonstrate proper setting of model string
values.
Model Strings Cannot be Set by Customers or by Resellers
Mismatches between HP e3000 A- and N-Class Server model strings and the actual processors installed in
the server may result in the server not successfully booting until an HP field CE properly sets the model
strings. Mismatches related to processor module frequencies are the most frequent reason for “model string
failure to boot” error messages.
If the actual number of processors in an HP e3000 A- or N-Class Server is greater than the number specified
in the model string, the number of processors configured at bootup time are limited to the number authorized
in the model string and a warning is issued to the user.
These bootup failures and warnings are most likely to occur if someone attempts to move processor modules
between servers or if someone attempts to convert an HP 9000 Server to be an HP e3000 Server. HP fields
CEs have been instructed to only reset model string values when repairing failing equipment or installing
properly purchased HP e3000 field upgrade kits or additional processor modules—never to reset the model
strings when someone has improperly added processor modules to an HP e3000 A- or N-Class Server.
For other HP e3000 Servers supported by MPE/iX Release 7.5, these bootup checks are not made at this time
but may be added in future releases.
The following table shows the model strings for all other HP e3000 Servers supported by MPE/iX Release 7.5
HP e3000 N4000 3-way 550 MHz Servers SERIES e3000/N4000-300-55
HP e3000 N4000 4-way 550 MHz Servers SERIES e3000/N4000-400-55
* All A-Class and N-Class Servers only use two characters in the last term to show frequency
